Be it lrnown that l, Chimenea l, Buizen, a ch iron ot the Unit-edStates, residing at vra'rusa in the county Onondaga and tate ot' New-lorl, have invented certain w and useful lmprovements in Adjustu bleClamping Devices, ot which the Alollovfiug is a specification.

This invention relates to adjustable means 'lor assisting in assemblingand temporarily holding the flexible hands which surround thetransmission drums ot Ford automobiles, while the rovers ot thetransmission casings are being either applied or removed.

rlhe object oi' the invention is to provide a. novel, simple and handyclamping device 'for transmission bands comprising similar arms whichare arranged parallel to each other' and which may be adjusted torregulating` the spacingof the said arms 'for aligning, drawing together,and holding the ends oil the bands in substantial registry, while otherparts are being applied. A. Jiurther object is to provide noveladjustable means tor connecting the said arms, said means comprising arod carried by one arm which is telescopically received by a tubecarried by the other arm, and a sleeve-nut which is slidable on said rodand engages the threaded split end ot the tube, by means ot which thetube may he solidly clamped to the rod tor holding the arms in differentadjusted positions.

l attain these objects by the means set forth in the detaileddescription which tollows and as illustrated by the accompanyingdrawing, in which- Figure l is a top view ot a portion oi thetransmission mechanism including` the trans mission drums and thecorresponding bands, to which my clamping device is applied. Fig. 2 isan enlarged plan view and partial section of the clamping device;showing by full and dotted lines the adjustable nature ot the same. Fig.f3 is an end view of the clamping device. Fig. l is a sectional viewtaken on line 4 4 ot Fig. 2. And Fig. 5 is a view of the split end otthe connectinn` tube.

ln the drawing 2. 3 and 4 represent respectively the reverse, low speed,and brake drums of the transmission assembly. These drums are usuallysurrounded by more or less tleXible bands 2, 3 and l, which are splitand their .ends are provided with radial.

bands are frequently relaxedl and tightened 'y up, and when they becomeworn to a certain extent the old bands are removed and new bands areinstalled..l ln order to per` torni this exchange ot the bands, thecover ot the transmission case (not shown) mustr be removed, land whenthe new bands are replaced on the drums, it is necessary to use someiorm of clamp, which is. usually applied to the extended lugs Q2, 3a,4ta, in order to hold them in the proper position relatively to thedrums until the cover is replaced. The present invention has for itsobject to provide a novel and simple cla-mp, which will now bedescribed: 5 and 5 represent similar straight arms, preferably made '7 5oit steel of any suitable cross-section, and ot equal length. Thecorresponding ends ot said arms are perforated, as at 5 to receive rods6 and 6', which are preferably round and are driven tightly into theperforations ot the arms. rlhe arms 5-5 are intended to be disposed andheld substantially parallel to each other, and they are also preferablyadjustable towards and away from each other, so as to vary theirspacing, torta` 85 oilitating the clamping and gaging ot bandlun's otdifferent spacings. To this end. the rods 6 and 6 are oil: differentlengths, and their combined length is intended to be less than thenormal spacing of the two arms.

The rod (i is preferably the shortest, and is employed tor supporting arelatively long tube 7, which is rigidly mounted on the short rod, withone end in contact with the arm 5. The opposite end vof the tube 5 95 isthreaded externally and this end is also split as shown at 6a, forfacilitating the contraction and expansion ot the said end. The rod 6 ispreferably of considerable length and slidably telescopes the split-endof the tube 7, for affording the aforesaid adjust ment of the arms 5 and5 towards and Jr'rom each other. In order 'to hold the arms of the clampin the diderent adjusted p ositions, as shown by the lull and dottedlines in Fig. 2, l provide a sleeve-nut 8 having a plain tubular portion8, which slidably fits the rod 6', and adjacent the said portion the nutis expanded, as at 8, and 1s 1nternally threaded for screwing on to the110 split-end of the tube 7. By `this construction and arrangement, asthe nut 8 is serewed on vto the tube, the split-end of the latter iseentraoted sufficiently to effect a tight Lgrip on the rod 6. Theenlarged portion 8 ol2 the nut is preferably knurled, as at 8b, forrendering the operators grip more effective when tightening andloosening the nut.

Having thus described :ny invention, what l claim, is-

l. A clamping device comprising similar arms of equal length, theCorresponding ends ot said arms being perforated, rods ot unequal lengthdriven into the periorations of the arms and extendingat rightanglestheien to, a tube rigidly mounted on the shortest rod and slidableon the longer rod and having` its free end externally threaded andsplit, ainda sleeve-nut slidable on the longer rod adapted when screwedon to the tube ina/asse to contra-Ct its split end for rigidly holdingsaid arms in various adjusted positions.

2. A clamping device including similar arms of equal length, thecorresponding ends ot said arms being perforated, rods driven into theperforations of said arms and eX- tending at right angles from thefacing sides of the arms, a tube telesooping said rods for holding` saidarms parallel to each other, said tube being rigid on one rod andslidable on the other rod, the free end of said tube being externallythreaded and the threaded portion thereof being split longitudinally,and a nut slidable on one of said rods adapted to engage the split endoi the tube for holding said arms in a number oli adjusted positions.

In testimony whereof l ailix my signature.
